Starting in March, service YouTube completely switch to a new design, which is now available only as recommended. After that, the classic version of the interface will be a thing of the past. As reported Google, a new version of the design appeared in 2017. She got a dark theme and layout in the style of Material Design.
It is stated that the classic version is devoid of these and other features. Among the latter, there is an improvement in the recommendation system.
After the discontinuation of support for classic design, users will be asked to switch to a new one. Refuse will not work.
The developers note that a browser update may be required if it is not compatible with the new version of the service. It can be suggested that this is required for older web browsers that still run under Windows XP.
